Abstract: A subjective and objective attribute weights integrated approach,based on 2-tuple linguistic information processing,for multi-attribute group decision making problem with linguistic attribute value and attribute weights value,is proposed.Firstly,subjective attribute weights are calculated by using the weighted averaging operator for linguistic 2-tuples.Secondly,an objective weights determining method based on the minimizing deviation is proposed.The deviation of attribute judgment of decision making group's calculated according to linguistic decision matrix.This deviation is larger,and it shows the disagreement of decision maker opinion is larger.Therefore,the at tribute weights value would be littler in order to enhance the consistency of group judgment.Then,subjective weight and objective weightare integrated into comprehensive weight.Finally,an example is given to illustrate that this method is effective and practicable.

Key words: multi-attribute group decision making, 2-tuple linguistic, subjective weight, objective weight
